Identifying A Black Swan Event
Based on the author's criteria:
- The event is a surprise (to the observer).
- The event has a major effect.
- After the first recorded instance of the event, it is rationalized by hindsight, as if it could have been expected; that is, the relevant data were available but unaccounted for in risk mitigation programs. The same is true for the personal perception by individuals.
An example Taleb uses to explain his theory is the events of September 11, 2001. 9/11 was a shock to many observers. Its ramifications continue to be felt in many ways: increased levels of government control; "preventive" strikes or wars by Western governments. The coordinated, successful attack on the World Trade Center and The Pentagon using commercial airliners was virtually unthinkable to many at the time. However, with the benefit of hindsight, it has come to be seen as a predictable incident in the context of the changes in terrorist tactics.

“And the serial continues:
Pain, expiation, delight, more pain,
A frieze that lengthens continually, in the lucky way
Friezes do, and no plot is produced,
Nothing you could hang an identifying question on.”
—John Ashbery (b. 1927)
“Our inherent human charity and our religious beliefs will be taxed to the limit. No poor, rural, weak, or black person should ever have to bear the additional burden of being deprived of the opportunity of an education, a job, or simple justice.”
—Jimmy Carter (James Earl Carter, Jr.)
“I have seen this swan and
I have seen you; I have seen ambition without
understanding in a variety of forms.”
—Marianne Moore (1887–1972)
“I feared these present years,
The middle twenties,
When deftness disappears,
And each event is
Freighted with a source-encrusting doubt,
And turned to drought.”
—Philip Larkin (1922–1986)
